WebIn addition to containing up to 90% ethylene, steam cracker C 2 cuts have from 0.5 to 3% acetylene. This highly unsaturated compound is undesirable in both chemical- and polymer-grade ethylene. The most elegant way to remove acetylene is via hydrogenation to ethylene.

Webn-pentane catalytic cracking was studied over a series of MFI zeolites with varying SiO2/Al2O3 ratios (30, 80, 280, 500, and 1500) using a fixed-bed reactor operated at temperature 550 to 650 °C. Web11. jún 2024 · Olefins production plants are large-scale plants, in most of which gaseous and liquid hydrocarbons are cracked to produce light olefins. The complex and large-scale nature of these plants makes it an utmost necessity to design and operate them with the use of computer-aided optimization and control methods. This review paper provides an … WebThe computational conditions for catalytic cracking of n-pentane are listed in Table 5. Conclusions. A systematic thermodynamic evaluation of the conversion of naphtha to light olefins is presented here, including the effects of cracking pathways and operating parameters on equilibrium yields.
